искра странная ИЛИ C NullPointerException

0 голосов
/ 06 апреля 2020

Я получаю странное исключение NullPointerException при вызове любого действия, которое обрабатывает все данные. Интересно, что 

val dOverallTotal = spark.read.orc("/path/to/file.orc/")
dOverallTotal.distinct.count // NPE!

Сбой с исключением nullpointer, тогда как интересно: 

val dOverallTotal = spark.read.orc("/path/to/file.orc/partition=part_value")
dOverallTotal.distinct.count // works just fine

прекрасно работает для всех доступных каталогов / part_values ​​при отдельной обработке?

Stacktrace ниже:
